| New approach to cosmic lithium in the early universe Posted: 07 Sep 2012 01:14 PM PDT Astrophysicists have explored a discrepancy between the amount of lithium predicted by the standard models of elemental production during the Big Bang and the amount of lithium observed in the gas of the Small Magellanic Cloud, a galaxy near to our own.  |
| Hubble resolves globular cluster M 4 into multitude of glowing orbs Posted: 07 Sep 2012 11:51 AM PDT A sparkling picture taken by the NASA/ESA Hubble Space Telescope shows the center of globular cluster M 4. The power of Hubble has resolved the cluster into a multitude of glowing orbs, each a colossal nuclear furnace.  |
| First look at structure of vital molecule Posted: 07 Sep 2012 10:16 AM PDT Molybdenum is an essential metal required in all living beings from bacteria to plants to humans. But as vital as this metal is, no one understood the importance of the structure of a vital molecule that interacts with molybdenum until now.  |
| Work with germ-killing copper could save thousands of lives Posted: 07 Sep 2012 10:15 AM PDT When Adam Estelle graduated from the University of Arizona's materials science and engineering program four years ago, he had no idea he would be involved in saving thousands of lives. Now, Estelle is working with technology based on copper alloys that kill bacteria, fungi and viruses. The metals can be fashioned into everything from IV poles to sinks to bed rails -- just about anything that is frequently touched in hospitals.  |
| Scientists cast doubt on Heisenberg's uncertainty principle Posted: 07 Sep 2012 09:51 AM PDT Werner Heisenberg's uncertainty principle, formulated by the theoretical physicist in 1927, is one of the cornerstones of quantum mechanics. The principle has bedeviled quantum physicists for nearly a century, until recently, when researchers demonstrated the ability to directly measure the disturbance caused by measuring a property of something, and confirm that Heisenberg was too pessimistic.  |
| World record set for highest surface area material Posted: 07 Sep 2012 09:51 AM PDT The internal surface area of just one gram of the synthetic material NU-110 could cover one-and-a-half football fields. That extremely high surface area could make the material especially promising for natural gas storage applications.  |
| Posted: 07 Sep 2012 06:58 AM PDT A multi-institutional team has directly observed electron hopping in iron oxide particles, a phenomenon that holds huge significance for a broad range of environment- and energy-related applications.  |
| Towards computing with water droplets: Superhydrophobic droplet logic Posted: 07 Sep 2012 05:20 AM PDT Researchers in Finland have developed a new concept for computing, using water droplets as bits of digital information. This was enabled by the discovery that upon collision with each other on a highly water-repellent surface, two water droplets rebound like billiard balls.  |
| The pocket radar: Thumbtack-sized distance and motion sensor developed Posted: 07 Sep 2012 04:23 AM PDT Today's parking assistant systems enable drivers to safely park their cars even in the narrowest of gaps. Such sophisticated parking aids require millimeter precision control and rely on precise all-around radar distance measurement. Researchers have now succeeded in integrating the necessary radar technology into millimeter-sized chip housings.  |
| Needle beam could eliminate signal loss in on-chip optics Posted: 07 Sep 2012 04:23 AM PDT An international team of researchers has demonstrated a new type of light beam that propagates without spreading outwards, remaining very narrow and controlled along an unprecedented distance. This "needle beam," as the team calls it, could greatly reduce signal loss for on-chip optical systems and may eventually assist the development of a more powerful class of microprocessors.  |
